Market power monitoring under open access system
In this paper, an engineering procedure is proposed for complete market power monitoring under open access system. Market power monitoring of any given system or network is done by using market power assessment and market power indices. For any given network, market power assessment is to identify which generation company (GENCO) raised their prices when the demand in the concerned area is ...

Software-based Neutron Flux Measurement Channel (NFMC)
For research nuclear reactors such as the TRIGA type, the design of Neutron Flux Measurement Channels (NFMC) has been based, mainly, on discrete digital electronic technology. The work presented here consists of the development of a new version of an NFMC whose aim is to measure the reactor power through six decades using the correlated signal of a wide range fission chamber. The correlation ...

Wavelet feature–based modular neural network for detection and classification of power quality disturbances
Disturbances such as voltage sag, swell, interruption and harmonics are very typical in a power system. Power quality monitoring should be capable of identifying these disturbances to initiate mitigation action and protect sensitive loads. This paper presents wavelet–neural network–based detection and classification of power quality disturbances. Wavelet transform has the ability to analyse ...

How to Monitor Data Centre Power Usage
There is now a huge desire amongst IT and Facilities professionals to adopt a suitable power management strategy, but implementation with existing tools can be extremely disruptive and problematic. Unless a new data centre is being built from scratch, installation of intelligent PDUs and inline power monitoring devices will ultimately result in considerable downtime and cost. However, a solution ...

Singular system analysis of the Local Power Range Monitor (LPRM) readings of a Boiling Water Reactor (BWR) in an unstable event
Singular system analysis is a successful technique to separate oscillating components from a given signal. A methodology is proposed to apply this technique to the signals obtained from the LPRMs of a boiling water reactor core and extract the contributions of the in-phase oscillation and the out-of-phase oscillations from the LPRM readings during an unstable event. This methodology has been ...

Characterisation of power quality disturbances based on wavelet transforms
This paper presents a new technique for detecting and characterising disturbances in power systems based on wavelet transforms. The voltage signal under investigation is often corrupted by noises, therefore the voltage signal is first denoised using wavelet thresholding and then wavelet transform is applied to the denoised signal. Using the first-level detail wavelet coefficients, the voltage ...

How power monitoring can improve sustainability, efficiency, and resilience
Earlier this year, U.S. President Biden announced “a new target for the United States to achieve a 50-52 percent reduction from 2005 levels in economy-wide net greenhouse gas pollution in 2030.” While governments around the globe make stronger sustainability commitments, more businesses are strengthening their own. This is confirmed in a 2020 KPMG survey that found 90% of “top ...

Electric power systems real-time monitoring and control
In recent decades, several improvements have been achieved in power system operation and control. The evolution was mainly in the development of computational and communication systems. Both areas allowed the analysis of complex models of power system operation and control that resulted in a more flexible system controlled in almost real-time mode. All these improvements favoured the change of ...

Online condition monitoring of electrical power system imbalance
Symmetrical components are of great importance in many applications in electrical power systems, such as power protection and condition monitoring. This paper presents a computer-based algorithm for online symmetrical components estimation. The proposed algorithm uses the samples of the phase variables (currents or voltages) to estimate the magnitude and phase angle of each phase phasor at each ...

Instrumentation and controls architectures in new NPPs
Instrumentation and control systems are the nervous system of a nuclear power plant. They monitor all aspects of the plant's health and help respond with the care and adjustments needed. Progress in electronics and information technology has created incentives to replace traditional analogue instrumentation and control 'I&C' systems in nuclear power plants with digital I&C systems. Digital I&C ...

Important Features in Solar Outdoor Light Fixtures
It is said that solar lighting may not be all it is cracked up to be because of the initial investment that one has to put up beforehand and the fact that you may not be able to use it as long as you would want inside your house. Homes have a lot of power needs so this may sometimes be a challenge if the use of solar power is not monitored. Solar lights take the going green initiative a step ...
